a citizen city, inthe county of New York and State of New Yorlqhavc invented certain new and useful linproi'elnents in' Ty}icwritiiig-Ha chines. M which the following is a speciltcation.

This invention rclut rhinos. and more spciizilly to sometimes known as word-:vuim-vng d w-vs.

as to typewrilinp; nia- Ihai are Thiinvention herein kl(-'(l'li""l 1*. applied to an Underwood typcwriting: machine. in which the re'voluhle platen 12-: jnnrnahul in a traveling carnage.

One primary utiiit oi such devices is to Qenahle words, such as headings. to he rap idly. and accurately centered upon a Work- In the structure illustratml herein, the peirriter carriage may he provided both with the usual pointer, which serves to indicate the position of the carriage,

and with an extra centering pointer. The latter may he adapted to he shifted he ina- 1 a. hirer or reun ting inw'han s so s of mampiziaiions or n i pulat ii that by a sh... tions thereof, the r shifted air-11;! the Mr! it to iii 'licate upon the usual scale at he point at which the writing is to he hegun if the center of the Writing is to come at the point indicated by the usual scale-pointer.

@ther featuresand advantages will hereinafter appear.

ln the usual Underwood typcwriting niarhine, the reroluhlc platen 1 is journalcd in a frame ll in the carriage 12. which travels i i-uni right to left. l1U3 lQ\'(ii t rharactenkcy L3 is depressed it carries down its lis'ylcver l-l t s ing iypu-lmr 2; upuardly and I't"iil"\ l 'i.il} so thin the trait; ll} thereon will print upon a work-sheet.l i. passedaround the platen.

To center any line of Writing: upon the Work-sheet 17, a centering pointer 26 may be positioned by a charactcrrounter 27. The character-counter comprises the lever 28, pivoted within the casing 29 of the counter,

fit)

advance the casing along the rack 30- fast to the Front har 31 of the typewriter carriage. The teeth of the rack are spaced on centers at half the spacing of the divisions on the scale 19, with the result that each depression of the lever 28 advances the casing half a letter-space. W hen,' therefore, the total number of letters and spaces in the desired line are counted off on the lever, the casing 29 will have advanced both itself. and the centering pointer 26, fast to it, half the letter-space travel of the typewriter carriage needed for Writing the desired line.

The easiest Way to center the desired line is to start the aforesaid counting with the of the line (illustrated as letter-space it] in Pig. 5). and when the counting is finished, note the position of the character-counter 27 on the scale 19 by it (i. 0., letter-space 30 in Fig. (5). then nioa'e the carriage to the right to bring the pointer lo to that position (Fig. 7). and begin writing the line from that position. Since this position ishalf the letter-spaces in the line. to one side of the first position of the carriage. the cen ter of the written line will fall at the first position of the carriage. and the writing will end at the Fig. 8 position'.

The connections, whereby the lever moves the casing along the rack, include a pawl 32. pivoted on an extension 33 of the lever 28 and a ratchet'wheel 3i. journaled on a transverse shaft 3?. which also forms the pivot of the lever 2b. The ratchet-wheel constitutes a pinion constantly in meslrwith the rack 30. The pawl 32 is normally pressed by a spring 35*. so that when actuated it goes into the teeth of the ratchet. and to enable the casing to be drawn to its left-hand position. the pawl 32 may be cammed clear of the ratchet by a spring 36, which swings the lever upward. so that an extension 36 of the pawl 32 rests on a cam lug 87 and the pawl is then clear of the ratchet-wheel. The lever may terminate in a thumb-piece 38, which is easily grasped, and be provided with :1 lug 39. which arrests it at the bottom of its throw by striking the top of the casing 29. The casing. surrounding the rack 30. may comprise a rear bar 412. having an L-bottoin 43 adapted to rest on the top of the front bar 31, and a front bar ll adapted to be held to the bottom 43 by screws 45 entering lugs -16. The front plate or bar ll has a lug 17 at each end, which extends downwardly and then in under the front bar 31, so that a set screw 18 threaded through each lug may be set up against the bottom of the front bar 31, thus holding the rack 30 in place. The rack may be fastened in the casing by screws 49 passing through it and threaded into lugs 5o projecting inwardly at the ends of the casing; and the casing may include a slot at the front, just above the bottom 43 cut at 51 from the bottom of the front plate 44, thus permitting the centering pointer 26 to be formed as an extension 52, held by screws to one side of the U-frame 53 within the counter-casing. The extension 52 projects outwardly through the cut and slightly upwardly. A further extension 54 of the extension 5:2. lies parallel to the front bar 31, thus permitting the centering pointer, When farthest to the left, to overlie and point to the same scale division as the pointer l8.

For convenience in a ssemhling. the front 55 of the asing 29 may be attached to the main body by screws 56 threaded into lugs 57 on the body. A stiff flat spring 58 fast to the bottom of the U-frame 53 holds the pointer 26 and its casing 29 upright. The U-frame may be held to the casing 29 by screws threaded into the U-frame and passing through holes 59 in an apron 60, depending from the casing 29 and connected thereto by a shelf 61, comprising an opening 62 to clear the head of the shaft 35. To center the teeth 30 accurately with reference to the scale 19, one of the set-screws 48 enters a depression 63, Fig. 2, in the under side of the bar 31.

Variations may be resorted to within the scope of theinvention, and portions of the im )rovements may be used without others.
